Since we know to make conversion I know you are wondering what US, UK, and AUS conversion system are and why can’t there be a standardized system for all bras to eliminate this problem of geographical difference. Let’s get to understand how this system works.


The US uses chest derived circumference band sizes in determining how they manufacture their bras for their consumers. The United States uses inches as a measurement of band size and cup size. Above all, it has a one-inch method on cup sizes. US cup sizes are represented by different alphabetical letters. Cup sizes in the US also begin with AA meaning a zero inch difference between the band and bust circumference and augment with the increase with the circumference. In US system Bands size may start at as low as 20. It is also notable that, US-style bra measurement in terms of alphabets runs from A-Z


Uk uses band sizes that have correspondence to chest circumference. Also, it uses Inches as a measurement unit. For example, if a lady says my band size is 30, then it corresponds to a chest circumference of 30. As seen in the US, the UK also uses a one-inch method for its cup sizes. What is the inch method mean for cups? It means that for that one inch of difference between chest circumference and bust circumference, the cup size increases by one inch. UK band sizes begin at the 28 and expand in terms of two inches as the size yields. While the cup sizes measurements start from AA that corresponds to 0 inches difference. Moreover, from there for any increase by an inch corresponds to one inch on cup size

Below is a one-inch method cup size for both UK and US systems. They are much comparable since they use inches as the unit of measurements and have the same letters when it comes to cup sizes however the US can have triple alphabets sizing such as DDD and DDDD a runs up to Z US UK table chart conversion inch method.

AUS system is much different from the two methods of bra sizing. It is mostly used within Australia and New Zealand. AUS sizing is described as the most compelling system in the manufacture of the brasserie. Cup sizes vary in terms of 2 cm as seen in the charts. Instead of using inches AUS style uses Centimeters in its measurements. Chest circumference is not regarded when it comes to band and cup sizes. AUS uses a dress size method for band size instead of under bust. AUS dresses are majorly manufactured to meet cup sizes of B and C only.

When using this system, one is prone to the incorrect measurement of Bra basing on the dress size. Apart from that is uses cap labeling in alphabets as used in the UK only from AA to DD and after there it uses European style cup labeling. AUS style does not have room for FF and GG type of bra cup sizes. Using AUS conversion chart to find an excellent bra size for your breast can be tedious enough if you do not understand the system comprehensively leading you to choose uncomfortable garment which disappoints you.

What is cup labeling, and how is it essential when it comes to bra size conversion among women. Cup labeling is an individualized system of labeling or placing substantial information within the bra to provide knowledge to the buyer. It is much essential feature in bra size conversion in such that it helps one easily identify the Cup sizes despite the manufacturer and location. Be it in the US, UK, Australia, and New Zealand, and the rest of the world.

Size labeling can be compelling and complicated for Aus and NZ women’s who are seeking international bra conversions since their systems are much different from others at a considerable margin. It has been seen among many local lingerie getting confused over cup labeling misinformation among bra and may lead to buying small cup sized bra or of different band sizes. It is thus making Cup labeling of much importance in fashion among Bra manufacturers.

To solve this issue of misinformation getting yourself a conversion chart and always getting an estimate of your cup sizes would be great to ensure the correct choice of bra that brings your taste and preference together easily anywhere. Cup labeling of the US is much different in comparison to the UK and AUS, which is the same. Cup labeling may be inaccurate, so it is always recommendable to measure always at the boutique before buying by use of a professional bra fitter to eliminate the possible doubts of unrealistic conversion.
